I have 2 older spray rigs that I'd like to find out what they may be worth. unit 1 has a 50 gallon tank and 100 gallon tank mounted on a skid that can slid into pickup bed. It has 2 electric hanney hose reels. Each reel has 300 or 400 feet of hose. Pumps are also electric. I am not sure what they are capable of, i.e. psi and gallonage. Hoses would most likely have to be replaced and/or inspected closely. unit 2 is the same as unit one, but has just a 100 gallon tank and 1 electric hose reel with an electric pump. I appreciate any ideas as to there worth.
